Movie maker 'not implemented' error msg when opening a MM project

Hi dear,

I worked several hours on a new version of a Movie Maker project. I saved it
on a regular time file, saved it even twice. But when trying to reopen the
file after the last save I recieved the error message 'not implemented'.

I'm using Vista and Movie Maker Version 6.0 (Build 6001 Service Pack 1).

Can someone helps me ?
